Someone always asks if it was worth it
Most HR teams can only answer it with a story, not a number.
More than two in five HR leaders believe a fifth or more of their leadership appointments in the past three years were mis-hires. Only 6% have never seen a poor people decision cost them, and three in ten have watched one cost the business revenue.
The hire who looked right on paper
Wrong-fit hires get recruited, paid, trained, managed and replaced. The cost lands in four budgets and is tracked in none.
The promotion no one could evidence
Strong performers move into management on reputation. When it does not work, nobody can point at what was missed.
The screening that eats your managers' week
Phone screens, sifting and first-round interviews absorb days of manager time that never reaches a cost-per-hire report.
See what you would get back
Choose what you want to see the numbers for: screening applications, hiring, identifying high potential or developing people. Answer two or three questions about your volumes and how you work today, and you get a modeled estimate built on validity research. Start again to try another.
Where recruitment ROI actually comes from
The same measure runs across hiring, development and talent mobility, so the insight compounds instead of resetting with every new tool.
Behavioral and cognitive assessment measures how someone will work. An interview measures how well they interview.
The same measure applied to every candidate and every promotion, so choices are comparable across teams, countries and years.
Phone interviews and manual sifting cost days per cohort and predict very little. One short assessment at the top of the funnel does the job in minutes, at any volume.
Replacing a wrong hire means paying the recruitment, onboarding and management costs again, plus the months lost in between.
Every decision carries the data behind it, which matters when a candidate, a regulator or a board challenges it.

Questions buyers ask
Start with costs you already carry: the salary and on-costs behind a wrong hire, the manager hours spent screening, and the roles sitting open. Assessment reduces all three. The return is the gap between what those cost now and what they cost after. Put your own numbers in.
More than the recruitment fee. Salary and agency costs are the visible part; lost productivity, manager time and team disruption are not. In recent research with 300 HR decision makers, 48% had seen team disruption follow a poor people decision, 34% higher attrition and 30% lost revenue.
Usually within the first hiring cycle. Jaguar Land Rover cut apprentice screening from three weeks to 48 hours and took 70% off screening costs. Virgin Media O2 had a new leadership selection process live across around 100 roles in three weeks.
Yes. Assessment data can be matched against performance once people are in role. One global specialty chemical manufacturer ran a predictive validation study after implementation, which confirmed prediction of job performance with no adverse impact by gender or ethnicity.
Yes, and that is where much of the return sits. The same assessment data supports promotion, succession and internal moves, so one completion informs decisions for years rather than for one vacancy.
